Product Summary

The TPS78601DCQR low-dropout (LDO) low-power linear voltage regulator features high power supply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in small outline, SOT223-6 and 5-pin DDPAK packages. The TPS78601DCQR is stable, with a small 1-μF ceramic capacitor on the output. The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (e.g., 390 mV at 1.5 A). Each device achieves fast start-up times (approximately 50 μs with a 0.001 μF bypass capacitor) while consuming very low quiescent current (265 μA typical). Moreover, when the TPS78601DCQR is placed in standby mode, the supply current is reduced to less than 1 μA. The TPS78601DCQR exhibits approximately 48 μVRMS of output voltage at 3.0 V output noise with a 0.1 μF bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR, low noise features, and the fast response time.
